Description

The Sketcher BSplinePolygon tool shows or hides the B-spline control polygon in all sketches. See this page for more information about B-splines.

The control polygon (green straight lines) connects the control points (marked with dark yellow weight circles).

Usage

There are several ways to invoke the tool:
- Press the Show/hide B-spline control polygon button.
- Select the Sketch → Sketcher visual → Show/hide B-spline information layer → Show/hide B-spline control polygon option from the menu.
